config-file
Short option: –f
Type: String
Default: dumpconf.conf
application-root
Short option: –r
Type: String
Default: None
application-name
Short option: –n
Type: String
Default: dumpconf
runtime-user
Type: String
Default: None
event-log
Type: String
Default: event-%a.log
preprocessor-binary
Type: String
Default: None
This option should refer to the full path to a binary or script that can preprocess configuration files prior to them being parsed by the datasource libraries.
Depending upon your choice of preprocessor, this allows variables to be substituted, extended logical conditions to be validated and generally reducing the configuration management requirements.
The preprocessor should take as its first argument the name of the file to process, and output a rewritten configuration file to standard out.
This feature has been extensively tested using the GNU M4 macro processor.
http-download-command
Type: String
Default: wget -nv -O -
HTTP config file download command
quiet-config
Short option: –q
Type: Boolean
Default: FALSE
verbose-config
Short option: –v
Type: Boolean
Default: FALSE
Report all messages for config files being loaded
ignore-missing-config-files
Short option: –i
Type: Boolean
Default: FALSE
Do not fail if configuration files do not exist
enable-threaded-callbacks
Type: Boolean
Default: FALSE
Release 4.4 of the Caplin Platform introduced a major new feature and an important pre-requisite for components that sit within the platform.
Prior to 4.4, all DataSource messages were serviced on a single thread and callbacks could be guaranteed to occur only on a single thread. With 4.4, multiple threads service DataSource messages, with the result that callbacks can occur on more than one thread and that more than one callback may be in progress at any point in time.
In order to maintain source compatibility with products built using older versions of DSDK, all callbacks into the application will occur on the thread that called ds_loop(), this naturally introduces a synchronisation point and will impact performance.
Enabling this option will remove the synchronisation point and performance will be increased, however the application must be threadsafe.

event-module

Acceptable Values:
Name | Value | Desc |
---|---|---|
epoll | 1 | Use the epoll event manager (Linux only) |
devpoll | 2 | Use the /dev/poll event manager (Solaris only) |
poll | 4 | Use the poll event manager (Unix only) |

iocomp | 16 | Use the IO completion event manager (Windows only) |
This option defines the default event manager used by DataSource threads. It's not recommended to change the default; DSDK will automatically find the best event manager to use on a given platform.
